This invention belongs to the field of drilling exploration and development, specifically relating to a method for calculating the remaining oil saturation of high water-cut reservoirs based on seepage patterns. It aims to solve the problem that existing methods for calculating remaining oil saturation require calculating well-to-well distances, making it difficult to quickly and efficiently quantitatively describe the remaining oil saturation at different locations. The method includes: collecting engineering parameters of the reservoir for which remaining oil saturation calculations are to be performed; constructing a quantitative mathematical model of seepage channels; calculating the seepage velocity based on the quantitative mathematical model; calculating the water cut based on the seepage velocity to obtain the water saturation; and then obtaining the oil saturation based on the water saturation. This invention eliminates the need to calculate well spacing and can quickly and efficiently calculate the remaining oil saturation at a specific moment for a grid node based on known parameters. This allows oilfield technicians to quickly, easily, and quantitatively grasp a relatively accurate distribution of remaining oil in sand bodies within a short time.
